The Compact Prefabricated Substation (250-2500kVA) is a modern, space-saving power distribution solution that replaces traditional indoor substations. This Compact Substation fully meets user requirements for energy metering, reactive power compensation, and customized high/low voltage configuration schemes, representing the development direction of small and medium-sized power distribution facilities.
With rated AC frequency of 50Hz/60Hz, maximum operating voltage up to 35kV and maximum operating current up to 5000A, this Compact Prefabricated Substation delivers stable performance across diverse scenarios. The Compact Substation is widely applied in industrial and mining enterprises, wharves, public facilities, high-rise buildings and residential areas. The Compact Prefabricated Substation is mainly exported to Asia, Africa and other regions, with professional OEM/ODM services available. The product complies with IEC60067, GB 17467-2010 and other international and national standards.
The Compact Prefabricated Substation adopts fully enclosed and fully insulated structure, ensuring safe and reliable operation.
This Compact Substation features simple operation, maintenance-free performance and low overall equipment cost.
The shell of the Compact Prefabricated Substation is firm, heat-insulated and well-ventilated, with stable anti-corrosion, dustproof and waterproof performance, and beautiful appearance.
The Compact Substation offers various shell material options, including steel plate, composite plate, stainless steel plate and cement plate, with protection grade up to IP67.
The Compact Prefabricated Substation is divided into three independent compartments: high voltage room, low voltage room and transformer room.
The high voltage room of the Compact Substation can be equipped with XGN15, HXGN17 or SF6 switchgear according to requirements.
The low voltage side of the Compact Prefabricated Substation adopts panel or cabinet-mounted structure, which can form customized power supply schemes, meeting functions such as power distribution, lighting distribution, reactive power compensation and energy metering. The main switch can be universal circuit breaker or intelligent circuit breaker, featuring flexible installation and easy operation.
The transformer room of the Compact Substation can be equipped with fully sealed oil-immersed transformer or dry-type transformer as required.
The Compact Prefabricated Substation supports three-phase four-wire or three-phase five-wire system.
High-quality three-phase tinned copper busbars are used, with high mechanical strength and excellent heat dissipation performance for the Compact Substation.
